    args = parser.parse_args()
    
    client = FnosClient()
    
    # 设置消息回调
    client.on_message(on_message_handler)
    
    # 连接到服务器(必须指定endpoint)
    await client.connect(args.endpoint)

    # 登录
    result = await client.login(args.user, args.password)
    print("登录结果:", result)

    # 发送请求
    await client.request_payload("user.info", {})
    print("已发送请求,等待响应...")
    # 等待一段时间以接收响应
    await asyncio.sleep(5)
    
    # 演示重连功能(手动方式)
    await client.close()  # 先关闭连接
    print("连接已关闭,尝试重连...")
    await client.connect(args.endpoint)  # 重新连接(现在会等待连接完成)
    result = await client.login(args.user, args.password)  # 重新登录
    print("重连登录结果:", result)
    
    # 或者使用内置的重连方法(需要先确保连接已断开)
    # await client.reconnect()  # 使用内置重连方法
    
    # 关闭连接
    await client.close()

# 运行异步主函数
if __name__ == "__main__":
    asyncio.run(main())
